FFC, FPC (Flat Flexible) Connectors

FFC and FPC connectors are electrical connectors commonly used in a wide range of applications. This type of connector can very easily be connected and disconnected, making it widely popular for applications requiring frequent connection and disconnection. A FFC/FPC, or flat flex, connector consists of a tape, or “web”, that has conductive pads running along it. Contacts on the connector clip the tape or web with the contoured pressure on the contact point causing the electrical contact.

Type

FFC/FPC connectors come in both male and female versions and are used for many different types of connections. They are most commonly used in computers and various control systems. The connectors may also come in either a straight or a right angle configuration. A right angle type consists of one lateral bend which allows the connector to fit into very tight spaces. This is ideal for limited space applications.

FFC / FPC connectors are used for a variety of applications including: LED display panels, laptops, medical equipment, consumer electronics, automotive, etc. They are increasingly popular in many portable applications, being extremely lightweight and having very small form factors. They have also become very popular in audio/video cables due to their very low EMI/RFI radiation characteristics.

Working Principle

The working principle behind FFC/FPC connectors is based on the insertion of the tape material between the contacts. This creates a secure abutment contact to the two mating surfaces. Each contact has a rounded shape which prevents any bearing forces on the contact.

When the connector is plugged in, the contact points are covered by the FFC/FPC tape material. As the connection is made, the pressure created by the two contacts begins to force the tape material to spread out. This allows the contact points to come into effect, providing a seating pressure. This seating pressure ensures a good electrical connection between the two mating surfaces.

Conclusion

FFC/FPC connectors provide a quick and reliable connection. They are small and lightweight, making them a great choice for a variety of applications. They are also very affordable compared to traditional connectors. FFC/FPC connectors provide excellent durability and have a long life expectancy.
